Both obey the same fundamental laws of physics & chemistry. All life is composed of one or more cells. Arise from the growth and division of other cells. Life is easy to recognize difficult to define. 7 characteristics are shared by all forms of life display order harness and utilize energy reproduce respond to stimuli exhibit homeostasis growth and development evolve the virus is unable to replicate by itself it is not alive. A termite cathedral emerges from the simple work of thousands of individual termites. Complex properties of life emerge from simple molecular interactions. The region around a star where water can exist in liquid state. Distance depends on energy output of parent star. Region, which in theory, is present around every single star.
